What ski?

so what are you looking for if you love your walls? Will you still use those or are they beat as fuck?

THere so beat up, no edge on the right ski. And a little to small

Well Volkl Walls are a medium-stiff full camber ski so other skis that are a similar shape and flex and have good durability include:

Armada AR7, ON3P Prestor, and Fischer Nightsticks.
I rode my AR7's constantly in park year round for over a year and a half and they only got two edge cracks, excellent durability. They're still skiable.
ON3P uses the thickest edges and bases which makes them last super long.
Fischer Nightsticks has a soft sidewall apparently which absorbs a lot of impact and makes them less prone to edge cracks and pull outs. I have a friend who abuses his and they still seem to be in good condition.

If you loved the Walls, then I would suggest the nightsticks. They also carve amazingly well. I have used armada skis of all kinds (AR6, AR7, Thall, Halo 2, etc) and I can definitely say while they do carve well for a park oriented ski ( and exeptionally well with the cap design near the tips/tails) they don't match up to the carving performance of a park ski like the Nightstick which has a race background.

ON3P I can't comment on since I have only seen them never ridden.
